TANK-FILLING VALVE.

T 0 all whom it may concern:

Be it known that we, J orm W. Boznman, a citizen of the United States,residing at Baltimore, Maryland, and JOHN T. Jones, a citizen of theUnited States, residing at Madras, in the county of Coweta and State ofGeorgia, have invented certain new and useful Improvements inTank-Filling Valves; and we do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in tank filling valves and moreparticularly to those intended primarily for use in connection withflush tanks.

One object of our invention is to provide a tank filling valve having arenewable valve member to be replaced when worn, and to make novelprovision for preventing the escape of water while renewing said valvemember, thus overcoming the neces sity of cuttingv oil the flow of waterthrough the entire supply line, as is now usually necessary.

Another object is to provide a valve of the character set forth, inwhich the auxiliary valve closes automatically when a portion of themain float controlled valve is removed for renewing a worn valve member.

A still further objectis to provide a valve of the type in question,which will be simple and inexpensive, easy to install, approximatelysilent in operation, and one in which wearing of the valve member isequalized by a novel mounting of the bell .01 valve body which carriessaid member.

With the foregoing in view, the invention resides in the novelconstruction and arrangement of parts hereinafter described and claimed,the descriptive matter being supplemented by the accompanying drawin s.

igure 1 of the drawings is a side elevation of the valve applied to aflush tank.

Fig. 2 is a vertical section with parts in elevation, showing theposition of parts when the tank is-completely filled.

Fig. 4 is a view similar to Fig. 2, but showing the manner in which thesupplemental valve prevents the escape of water when renewing the valvemember or gasket of the fioat controlled valve.

Fig. 5 is a horizontal section on the plane of the line 5-5 of Fig. 2.

Fig. 6 is a side elevation of the hollow passage member, a portion ofsaid member being in section.

Fig. 7 is a vertical section partly in elevagkilll, of the main valvecarrying body or In the drawings, wherein for purposes of illustration,we have shown the preferred form of our invention, the numeral 1designates a hollow cylindrical passage member adapted to pass throughthe bottom 2 of a flush tank, the lower end of said passage member beingprovided with a suitable couplingii for attaching the water supply pipe4. ny suitable means could be employed for securing the passage member 1in place, but it is preferably provided with an integral collar 5 torest on the tank bottom, and with a clamping nut 6.

The upper end of the passage member 1 is provided with a valve seat withwhich a valve member 7 coacts, said member being carried by a downwardlyclosing body 8. The valve member 7 is preferably in the form-of a gasketof leather or other suitable material; said gasket is received in asocket 9 in the upper end of the valve carrying body 8, and a plug 10 isthreaded into said socket, against said gasket to retain the lattcrinplace. The valve carrying body 8 is provided'with a suitable opening 11exposing the lower surface of the valve member or gasket 7 for properpresentation to its seat, and in the preferred embodiment of our device,we construct said valve carrying body in the form of a bell whose wall12 is loosely slidable and rotatable on the upper end portion of thepassage member 1, being loosely guided by suitable lugs or the like 13.When the valve member 7 is unseated, the water discharges into the belland shoulders to clamp said seat in place, a float an inwardly extendingstem carried by said actuated sleeve slidable loosely on the pasplug andpreventing closing of said check 10 sage member and having a closedouter end valve until said plug is removed to renew provided with avalve disk coacting with said valve disk.
